阅读说明：本技术 用于增材制造的图案化光的开关站射束路由 (Switchyard beam routing of patterned light for additive manufacturing ) 是由 詹姆斯·A·德姆斯 弗朗西斯·L·利尔德 埃里克·图姆尔 于 2018-05-11 设计创作，主要内容包括：一种用于增材制造的方法和装置,其涉及高效率、能量束图案化和射束操控以有效且高效地利用源能量。在一个实施例中,不想要的光的回收和再利用包括由一个或更多个光阀产生的多个光图案的源,其中多个光图案中的至少一个光图案由被拒斥的图案化光形成。图像中继装置被用于引导多个光图案,以及射束路由系统接收多个光图案,并分别将它们引导向粉末床上的限定区域。(A method and apparatus for additive manufacturing that involves high efficiency, energy beam patterning and beam steering to efficiently and effectively utilize source energy. In one embodiment, the recycling and reuse of unwanted light includes a source of a plurality of light patterns generated by one or more light valves, wherein at least one of the plurality of light patterns is formed by rejected patterned light. An image relay device is used to direct the plurality of light patterns, and a beam routing system receives the plurality of light patterns and directs them to respective defined areas on the powder bed.)
